How do you represent trhis distribution blocks in your CAD / IEC schematics?

Hey everyone,

I’m currently working on a control panel project (using SEE Electrical, IEC standards) and I’m looking for some advice on best practices.

I have a power distribution block (see attached photo). The incoming lines are 2x25mm² to this block, I have multiple smaller lines going out to various consumers (fuses, motor starters, etc.).

I want to avoid making the schematic look like an unreadable spiderweb. I'm torn between a few approaches and would love to know your company standards:

  1. Visual representation?
  2. Wire Numbering?

Of course, all outgoing lines dropping in size will hit a protective device immediately, but I want the distribution itself to be crystal clear.

How do you guys handle this in your daily workflow? Any screenshots of your schematics would be hugely appreciated! Thanks!
